Vibration Analysis Technique for Machine Fault Diagnosis

Introduction of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

Machines have become an essential part of every sector of life from the health sector to the industrial sector. All the processes are carrying out by using the devices. Therefore, it is necessary to test the condition of the equipment before launching into the market. There are multiple techniques for quality checking and fault detection of the condition of the machine. Vibration techniques are one of the basic technique that is used for machine condition by analysing the vibration monitoring. These techniques are widely used as fault detection. This assignment is based on condition monitoring vibration techniques. Theprocess of carrying out the assessment would be evaluated in the assignment, along with the advantages and disadvantages of condition monitoring vibration technique. Condition monitoring vibration techniques are widely used for the rotatory machines. As the use of the rotatory machine is increasing, and there is a need to carry an assessment of the rotatory machine and the detection of the fault analysis.

Main body of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

 The rotating machines have the chance are the unbalance force produced in machine.  It would create the various faults in the rolling elements bearings, and it causes the failure of the rotating machinery.  The bearing faults would ultimately generate many problems that cause the improper functioning of the rotating machines, and it is used widely in small as well as extensive industrial application.  All these fault issues are rotating machinery can be indicated and present in the dorm of the vibration of the simple harmonic motions with the amplitudes of the vibration signals. All the faults and the detection of the rotating machinery need the proper time where machines can be detected. The maintenance of the rotating machinery, the vibration condition techniques is more significant through the whole life span.  This fault in the rotating machinery increases the life of the rotating machinery.

Procedure the faults are created by using the multiple parameters that may be related by cyclic loading of the machine, the tolerance limits are given in the rolling bearing segments in between the shafts in the rotating machinery. The insufficient lubrication is given to the machines with the passage of the time, and it would cause the failure of the devices. The other reason that causes the failure of the machine is the manufacturing faults in the use of the low-quality material, the size of the material, etc. The aforementioned issue causes the collapse of the rolling element bearing.  The defect would be in the form of distributed and localised defects. In the condition monitoring techniques, all the errors can be measured by using the specific vibration pattern. This pattern is known as the spectrum of frequencies.  The spectrum frequencies are generated in the vibration of various amplitude according to the energy level, and the frequencies are characterised by the inner and outer race. The analysis can be done in the form of the analytical, numerical and experimental method(A & S, 2018).

Experimental test of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

The experimental test is used to analyse the condition monitoring in the vibration analysis,  the USB piezoelectric accelerometer of 33Mv/g is taken as the vibration parameters in the data and frequency spectrum along with x and y-axis.  The device is connected to the accelerometer, and the algorithm of El-Calc is used to see the vibration spectrum.  Vibration signal us obtained in FFT using the accelerometer. This significant frequency has the spectral calculation for the multiple ranges from minimum to maximum. The softwareis run the calculations for different process n the time over the cycle.  The accelerometer is placed over the bearing top and the speed of the shaft measures through the other device tachometer. In this procedure, the motor shaft and rotating shaft are linked with the coupling, and it reduces the high amplitude that is generated with the motor. The speed range of the motor is in between 0-3000 rpm, and the dc power supply is given that vary the voltage of the speed up to 900 rpm.  It is all about the procedure of the experimental techniques of the condition monitoring vibration analysis (A & S, 2018).

Advantages of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

The advantages of the preventive approach, and the rotating machines, and the forces include the different segments in the different failure.  The various problems may cause problems in a genuine problem. There are multiple advantages of the new techniques of the vibrations and artificial intelligence to analyse the machine condition-based monitoring system.

Cost-effective

 The vibration analysis in the condition monitoring analysis,and it helps the reactive and preventive measures taken to analyse the fault in the SCADA system, and it ensures the cost-effective measures. For instance, the CBM regime usesabroad range of machines, and it prevents the high up-front the cost of CBM system.

Integration of condition-based monitoring

The use of technology can be converted into the traditional to the new phase of the technology and change the condition-based monitoring. The new method is changed into the computerised usage method(Palmer, 2019).

Disadvantages of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

·         There is the cost for training the staff, and competent staff is required to analyse the techniques and performance of the work.

·         The uniform faults are not detectable with the condition-based monitoring

·         The survival of the condition based sensor would not be induced in the operating environment

·         It needs the asset modifications regarding the sensors

·         There is an unpredictable time for the maintenance of the instruments(FT, 2019)

Conclusion of Vibration Analysis Technique for Machine Fault Diagnosis- Rotatory machine

vibration analysis is used to check the faults and gaps of the machinery, and it helps to prevent any incident regarding operating activities of the mechanism.  From this report, it has been concluded that condition-based monitoring is widely used for the assessment of the rotatory machines and the experimental analysis of the control based analysis would be implemented to know the bearing faults of the devices. The procedure is elaborated with the figures along with the advantages and disadvantages of the technique.
